Far better than any internet based review or even most discussions is a side by side comparison out on the trail when one of your companions brings along the Shiny New Toy and everyone else can gawk,pinch, and kick the tires to determine if it is the next Indispensable Item.

I can remember gasping in awe, tugging on my forelock, at the first stuff sack, first Kelty frame pack, first Primus, etc. and experiencing a convincing demonstration of their utility.
